ROLLER FOR GRAVITY-CONVEYERS, &o.

Application filed June 10, 1918, Serial No. 239,148.

To all whom it may concern:

Be it known that I, MORRIS U. BERNHEIM, a citizen of the United States, residing at Cincinnati in the county ofI-Iamilton and State of and useful Improvements in Rollers for Gravity-Conveyors, &c., of which the follow ing is a specification.

This invention relates to rollers and more particularly to rollers of the type used in gravity conveyers, wherein the packages to be conveyed rest directly upon and are in almost constant contact with said rollers.

The object of the invention is to provide a roller constructed in such manner that it will be markedly Wear resistant, will not become battered out of shape by hard usage, will be in large measure noiselessin operation, will retain its alinement through a long period of use and may be constructed at a very low cost.

In achievement of the foregoing objects I provide a roller comprising an outer metallic shell, a body portion formed of a suitable non-metallic material, as wood, for example, arbors by which the'roller may be mounted for rotation, end cups through which the arbors pass and means uniting the several parts in a simple and eflicient way. The metallic shell provides a wear resistant element which will give long life to the roller. The Wooden body not only serves its function as a core to carryv the arbors but the presence of this complete filling in the shells renders the rollers less drum-like and consequently less noisy in operation while the metallic cups engage the arbors and support said arbors and prevent the openings in the ends of the wooden cores, into which the arbors project, from becoming enlarged to such an extent as to cause the rollers to wabble, as has sometimes been the ease with wooden rollers of ordinary construction.

Further objects and advantages of the invention will be set forth in the detailed de scription which now follows:

Referring to the drawings:-

Figure 1 is a View, partly in longitudlnal section and artly in elevation of a roller constructed in accordance with the invention and wherein the metal shell extends the full length of the roller. j,

Fig. 2 is a like view illustratlng a slightly different method of connecting the parts.

Specification of Letters Patent.

Ohio, have invented certain new Patented Mar. 29, 1921. Renewed September 22, 1919. Serial No. 325.522.

3 is a like view of a structure comprising a wooden roller, part of which is exposed, but the portions whereof, adjacent the ends, are protected by metal caps.

Fig. 4 is a sectional view of one of the cu shereinbefore described and 1g. 5 is a face view of said cup.

Like numerals designate corresponding parts in all of the figures of the drawings.

Referring to the drawings and particularly to Fig. 1, 5 designates a hard wood core or body portion that is surrounded by a steel shell 6. This steel shell extends outwardly beyond each end of the core 5 a sufficient distance to form a recess within which cup shaped members 7 are received. These cup shaped members are preferably provided with inturned flanges 8 which de fine central openings formed in said members. Stub shafts or axles 9 project through these openings and enter openings 10 formed in the opposite ends of the core 5. The axles or stub shafts 9 are serrated as indicated at 11 and these serrated portions receive the correspondingly shaped ends 12 of dowels 13, said dowels passing through the shell 6, through the core 5 and engaging the serrated portions 11 of the shafts as stated. The heads of the dowels 13 are flared as indicated at 13* and are countersunk in the shell.

In assembling the construction illustrated in Fig. 1, the core 5 is first driven into the steel shell. The cup-like members 7 are then driven into the open ends of the shell until they abut against the ends of the core 5, after which the shell is spun over as indicated at 14 to thereby secure the cup like members firmly in place and to hold the core 5 against endwise movement with re spect to the shell 6. The stub shafts or axles 7 are then driven into place and'in order to aid in securing the shafts in position the openings defined by the flanges 8 are made slightly smaller in diameter than the shafts, so that the material of the flanges must spring as the shafts are driven into position. After the shafts are in place the dowels 13 are put into place as hereinbefore set forth.

In the construction illustrated in Fig. 9. the steel shell 6" is substantially equal in length, to the core, and the ends of the core are slightly reduced as indicated at 15 to permit cup-like members 16 to be driven upon said reduced ends. The stub shafts 17 are like the stub shafts 7 and are serrated at 11, as in the former case. In this construction dowels 13 traverse the steel shell, the cup-like members 16, and those portions of the core which project into said cup-like members. The inner ends of these dowels are serrated at 12 to adapt them to engage with the serrations 11. The cuplike members 16 are provided with plain openings 18 through which the stub shafts 17 pass, said shafts entering openings '10 of the body portion or core 5 of the roller.

The presence of the steel shells in the above described construction renders the rollers wear resisting to a marked degree, while the fact that the interiors of these steel shells are completely filled, deaden the noise which would otherwise be created by the use of hollow,metallic rollers.

In the, form of the invention illustrated in Fig. 3,1 have illustrated a wooden roller 20, the central portion of which is concavcd as indicated at 21. In rollers of this type,

' packages being conveyed are supported. upon the shoulder 22, at the opposite ends of the rollers. When rollers of this type are to employed, cup-like caps 23 are driven upon the opposite ends of the rollers, said rollers being reduced in diameter at 24-, to such an extent as to leave the outer surfaces ofthe caps flush with the shoulders 22. The caps 23 are provided with central open ings 25 and the roller is provided with openings 26 in alinement with the openings 25 of the caps, which openings serve to re Y ceive stub, shafts oraxles like those dcscribed withrespect to Fig. 1 and to which the same reference characters have been applied. In-thisconstruction dowels 2? traverse the caps 23 and those portions of the roller 22; which lie within said capsv and the inner ends of these dowels engage the serrated portions 11 of the shaft'or axle. lt willbe noted that the serrated portions upon the shafts are adapted to be engaged by the dowels at a plurality of points upon the surface of the shafts, both longitudinally and circumferentially. This renders it unnecessary to accurately aline any exact spot upon or part of the shaft with the inner end'of the dowel.

It will be understood that these shafts or axles serve to mount the rollers in conveyor frames 28 which are usually, though not necessarily, of angle iron. 7

While the invention is primarily intended for "use in 7 connection with the rollers of gravity conveyers, it is apparent that rollers constructed in accordance therewith may be used in many other relations, such for example as idlers or guide rollersfor belt conveyers, those features which lend rigidity,

strength, long life and freedom from noise being manifestly of value in the relation indicated as well as in conjunction with gravity conveyers.

While the several construrtions shown and described provide rollers having the advantages recited, it is to be understood that the constructions illustrated in the drawings are merely exemplary and that the principles involved form the real gist of the invention irrespective of the particular mechanical form in which they may be embodied. It is therefore to be understood that the invention is not limited to the precise construction set forth, but that it includes within its purview whatever changes fairly come within the spirit of the uppended claims.
